AUTOMOBILE BOAT.

To allwliom it may mm.-

Be itknown that I, FRANK FnnDRIcH MATTMANN, a subject of the King ofGreat Britain, and resident of the city of Montreal, Province of Quebec,in the Dominion ofCanada, have invented certain new and usefulImprovements in Automobile Boats;

andv I do hereby declare that the following is a full, clear, and exactdescription ofthe same.

The invention relates 'to an automobile boat as hereinafter fullydescribed with the aid of the accompanying drawings in which- Figure 1is a side elevation of the automobile boat according to the invention.Fig. 2 is a sectional perspective view of the boat at anintermediatepart. Fig. 3 is'a detail side view of the propellingmechanism. Fig. 4 is an inside elevation of the door locking means. Fig.5 is a cross section through the rim of one of the wheels. Fig. 6 is adiagrammatic view. of the brake mechanism. Fig. 7 is a sectional planview of one side of the body adjacent to the front wheels.

The object of the'invention is to devise a mechanism capable of travelon land or in water and which will therefore be of great use for warfareand pleasure purposes.

Some of the principal features of the invention are a body in 'theformof a boat hull having water tight doors in its sides and an engine atthe front and with a common driving shaft for water and land ex tendinglongitudinally to and through the rear end which is provided with a wormdrive to the rear wheels and a propeller for water drive. Spring wheelssupport the hull on land at each end and the axle of the front wheelsextends through packing glands in the hull.

The use of spring wheels in a machine of this description is averyuseful feature as the necessary resiliency for travel on land is thusobtained in an extremely effective manner permitting great simplicity inthe construction and arrangement of the driving and steering mechanism.

Referring to the drawings, 1 indicates the body having the counter 2 atthe rear end beneath which the rear axle 3 extends and the propeller 4rotates.

The body 1 is very much the same shape as an ordinary boat, but isprovided with water tight doors 5 in its sides providing an entrance tothe body. The openings for Specification of Letters Patent.

the doors'are each provided with flanges 6 extendingtherearound on theoutside and having a washer 7 inside of said flanges. Each door 5 has aflange 8 all around adapted to abut the washer 7 in the closed positionto form a water tight joint. The doors 5 are supported by hinges on oneside and are each clamped to the closed position by a locking bar 9engaging the staples 10 secured to the inside of the body on oppositesides of the door opening. The central portion of this bar is screwthreaded and a bolt is pivoted on thedoor and provided with a screwthreaded shank engaging the thread of the bar. The bolt is operated bythe hand wheel 11 forming the head thereof. The locking bar 9, it willbe se en must be turned so as to disengage the staples in order to openthe door. To close said door, the ends of the bar 9 must engage thestaples 10 and the hand wheel 11 on one end of the bolt is rotated,while the other end of the said bolt will hermetically push the doorclosed as the thread will engage the central screw portion of thelocking bar.

12 are the front wheels mounted at the ends of afront axle 13 andsteered by a steering rod 14 in the same manner as an automobile, but inthis case the axle and the steering rods extend through packing glands1'5.

It must be noted that there are no supporting springs on the front axlewhich has no lateral movement relative to the body, the necessaryresilience for travel on land being obtained through the medium of thewheels which are spring wheels of any well known construction such asshown.

The counter 2 provides the wall 16 at the rear end of the boat to whichis attached a gland 17 through which the driving shaft 18 projects, saidshaft extending along the bottom of the boat and being driven by asuitable engine at the front end. The outer end of the driving shaft 1.8is provided with a worm 19 engaging a gear 20 rigidly mounted on therear axle 3, said worm and gear being suitably inclosed in the case 21.

The mud guards 25 and platform 26 are secured to the body by the hinges27 in order that they may be folded back against the side of the bodywhen the device is used as a boat.

The spring wheelslQ and 2a are provided with. detachable rubber treads28 each fitting in a groove formed by a'flange 29 and a detachableflange 30, in order that the ma chine might be used on railway railswhen the tire 28 and flange 30 are taken off.

For electrically lightin the lamps 31, a drive may be taken from theshaft 18 to an electric dynamo 32 and another drive may be also obtainedfrom the same shaft to an air pump 33 for supplying air to the cylinders34 of abrake apparatus operating a-band '35 on the rear axle 3. a

In the present invention, the parts outside the body are reduced to aminimum owing to the provision of axles rigid with the bodyqand theprovision of spring wheels,

" andI wish it-to be understood that the details not mentioned hereinmay be anything suitable so long as the main features are ad-' her'ed toas claimed in the following claims for novelty. 7

e The front wheels may be mounted at the ends by brackets extendingfromv the side of the hull instead of on an axle extending through thehull and in this arrangement only the steering rod'would need to extend"through packing glands. v i

What I claim is i 1. In an automobile boat for use on land and water,the combination of a hull having a counter, at the rear, an enginemounted in the hull, opposite stufling boxes in the sides Copies of thispatent may be obtainedfor said stufling boxesand spring wheels mountedat the ends ofsaid axle,"a rotatable rear axle extending across the hullbeneath said counter and rigid means for supporting said hull-on theaxle, sprlng Wheels on the ends between said shaft and rear axle andsuit- 7 able steering means. a

2. In an automobile boatifor use-on land of said hull, a front axleextending through and water,;the combination of a hull, an enginemounted in the hull, opposite pairs of stuffing boxes in the sides of"said hull at the front end, a front axle extending through oneopposite'pair of stufling boxes," and spring wheels mounted. at theendsof SaId'ELXlG, steering means including a'steering rod extendingthrough'th eother opposite pair of stufling'boxes, a rear axle and Vrigid supporting means therefor,' spri ng 1 wheels on the ends of saldaxle,'a drlving shaft extendlng from said 'engine 'through the'hullbeneathsaidrear axle, worin driving'means betweensaid driv ng shaft andaxle, a propeller mountedbn'the projecting eratively connected to theaforesaid steering Signed at Montreal, Quebec, Canada, this 7 16th dayof September, 191 f.
